Unpredictable Cyclone bug

Asylamb

I'm playing Green TotP with Sarkhan Unbroken and the following deck:
---
Creatures
1. Gaea's Revenge
2. God-Eternal Rhonas
3. Shefet Monitor (Cycling)
4. Yidaro, Wandering Monster (Cycling)
Spells
5. Hazoret's Undying Fury
6. Turntimber Symbiosis
Supports
7. Fetid Pools (Cycling)
8. Ominous Seas (Cycling)
9. Sheltered Thicket (Cycling)
10. Unpredictable Cyclone (Cycling)

The point being if I don't get HUF early on, I cast Unpredictable Cyclone to Cycle away the non-bold cards and get one of the bold cards with full mana (up to 3 cards a turn).
I only use this deck for Green TotP and last time I don't remember having any problems. Today I noticed that when you Cycle a support while Cyclone is on the board, that card would get exiled, Cycling mana cost would be drained, Battle Log would show that Cyclone triggered but I wouldn't get a free card, I would just exile a card like normal plus drain some mana from my hand.
When Cycling creature cards, Cyclone worked as intended.

Doesn't Unpredictable Cyclon give you a card with the same card type but without cycling? So exiling a support would give you a support. Seems to me your deck simply doesn't include a support without cycling to be fetched by exiling a support. Or am I missing something?

Oh, that must be it. #rtfc Thanks.
